How to write a Kazakhstan number in E.164

1. Remove spaces, dashes, dots and brackets so only digits are left.
2. If the number starts with the trunk prefix 8, remove it. It is only used when dialling inside Kazakhstan.
3. Put +7 in front. The result has 10 digits after the country code for a mobile.

So 8 (771) 000 9998 becomes +77710009998. E.164 is the format SMS gateways, dialers and most CRMs store; see the E.164 format explained for why.

Mobile or landline?

Kazakhstan allocates separate number ranges to mobiles and landlines, so a numbering-plan check reads the line type straight from the digits, for free. That type describes the range the number came from. It doesn’t prove the number is connected today.
